IMPROVEMENT IN LAMP-EXTINGUISHERS.

TO ALL PERSONS TO WHOM THESE PRESENTS SHALL COME:

Beit known that I, WILLIAM P. BENNETT, ofEast Pepperell, in the countyof Middlesex, and State of Massachusetts, have4 invented a new anduseful Kerosene-Burner Extinguisher; and do hereby declare the same tobe fully described in the following specification, and represented inthe accompanying drawings, of whieh Figures 1 and 2 are vertical and.transverse sections of a burner provided with my invention, thesesections being taken in planes at right 'angles to each other.

Figure 8 is a top view,

Figure 4 an end view, and v Figure 5 a side view of the wick-tube andits appliances.

The principle of my invention is to .be found in the application of' tworollers to the wick-tube, so that the said, rollers may operate with andbe operated by the wick,substantiallyin the manner as hereinafterexplained. Also, in the combination and arrangement of slotted arms withthe two rollers and the wick-tube, or with an additional or oap-tube4orcollar to fit upon the wick-tube,'as hereinafter set forth. Also, in thecombination, as well as the arrangement, of two air-stops with therollers and wick-tube, when such rollers are applied to such tube so asto be operated by and`with the wick, in manner as hereinafter described.

Alin the drawings, A. denotesthe body, B the wick-tube, and C theair-deflector of a common kerosone-lamp rs, a a, whose disposed withrespect to the wick-tube e top of such tube, to pass between thevjournals are arranged in the slots c c c c of four slotted arms, b b 6ZJ, in such manner as to enable the wiclqwhile being elevated above thtwo rollers, and separate them or move them asumier,l wick is nextdepressed, the rollers, by their gravity, may fall and come or approachtogether again over the, topof the wick, so as to extinguish any flamethereon. Each of the arms stands obliquely with respect to the top ofthe wick-tube, in manner as represented. They may project directly fromthe wick-tube, or from a extend I place a collar, g, provided withprojections or stops It h, which, when the rollers fall in their lowestpositions, extend top of the wick, they will at once extinguish theflame.

alongside of them, and up or nearly up to them, when they are in theirhighest positions. These guards or stopsV prevent the wick from becominginflamed below the rollers, and prevent air from passing below therollers to the wick, so as to aid in iniiaming it below the rollers.Besides this, the guards or stops are advantageous in other, respects.-By moving the wick vertically by the ordinary wick-elevator orspur-pinion E, fixed on a 'gross-shaft, we eaneect the necessarymovements of the rollers, and, as Vthey drop by their gravity over theI"clai`m the'application of the two rollers a a' to the wick-tube of theburner, so that the said rollers may operate with andthe-operated by thewick, substantially 4in manner and for the purpose set forth.

I also claim the eombination and arrangement -of the slotted arms b bwith the two rollers a a, and the i and the wick-'tube, applied andarranged together substantially as eXplained.
